Anomalous negative phototransistors in which the channel current decreases under light illumination hold potential to generate novel and multifunctional optoelectronic applications. Although a variety of design strategies have been developed to construct such devices, NPTs still suffer from far lower device performance compared to well‐developed positive phototransistors (PPTs). In this work, a novel...
Negative Phototransistors
In article number 2201364, Huipeng Chen, Jishan Wu, Fangxu Yang, Wenping Hu, and co‐workers report an ultrasensitive negative phototransistor based on 1D/2D molecular crystal p–n heterojunctions. This novel device exhibits a variety of intriguing properties, including superior performance parameters, accurately controllable threshold voltage, and ultrasensitive detection...
